, LEVEL.

Application filed January 14, 1925. Serial No. 2,332.

This invention relates to a leveling instrument.

It is aimed to provide a novel construction adapted for operation by aweight and designed tobe read from opposite sides.

Another object is to provide a novel construction wherein the indicatorand its pendulum are mounted in a novel manner by a casing whose partscoact with the stop or body of the level to secure the various componentparts of the instrument together.

Additional objects and advantages will become apparent from aconsideration of the description following, taken in connection with theaccompanying drawings illustrating an operative embodiment.

In said drawings Figure 1 is a view of the instrument in side elevation.

Figure 2 is a sectional view taken on the line 2,2 of Figure 1.

Figure 3 is a fragmentary view mostly in side elevation with the dialand associated parts at one side removed.

Like reference characters designate like or similar parts in thedifferent views.

In carrying out the invention, a stock or body 10, of wood, metal or anyother appropriate material is provided with an opening, for instance,centrally thereof to accommodate the working parts. Disposed Within thesaid opening is a casing 11 comprising sections 12, of substantiallysimilar shape and removably telescoped with each other as shown. Thesesections have flat disks 18 con stituting their side Walls andexteriorly having delineations or calibrationsld to indicate angles. Theouter edge portions of the disks or dials 13 extend beyond the curved ortelescoping walls 15, which complete the sections 12, as indicated at16. Said portions 16 overlap the opposite sides of a rib 17 forming partof the stop and extending inwardly of the remainder of the opening. Thesections 12 are secured together and to the stock by means of detachablebolts or other fastenings 18 which pass through the portions 16 and rib17.

Journaled in the disk 13 in any suitable manner, as on ballbearings, orby means of jewel bearings, or otherwise, is a spindle 19 from which apendulum or weight 20 of any suitable size, shape or material issuspended by an arm 21 rigid with the spindle and with the pendulum. Thespindle extends beyond the arm 21 in order to pass through and bejournaled in the disks 13 and beyond such disks have indicators orpointers 22 screwthreaded or otherwise detachably connected thereto. Washers 25 may be interposed be tween the disks 13 and arm 21, andmounted on the spindle 19.

The edge portion about the opening aforesaid, is recessed as at 26 oneach side of the stock to form a seat for transparent panels 27 ofglass, celluloid or the like. Said panels are removably secured in placeby metallic rings 28 overlapping the same and detachably connected tothe stock as by means of screws 29 passing through the rings and intothe stock.

In use, the stock is placed. in engagement with the desired surface andaccording to the angularity of the stock, the pendulum 20 will move thespindle 19 as such pendulum seeks the vertical. Since the pointers orindicators 22 move with the spindle 19, they indicate the level orangularity of the said surface in combination with the calibrations 14:.These indications may be observed from opposite sides of the instrument.

Various changes may be resorted to provided they fall within the spiritand scope of the invention.

I claim:

A leveling instrument comprising a stock having an opening, a rib on thestock extending into the opening, a casing having sections, each sectionhaving a flat wall. constituting a dial and overlapping a side of saidrib, each section having an annular wall extending inwardly from thedials, said annular walls being in telescopic relation and occupyingsaid opening, the outer portions of said dials and rib havingregistrable openings to aid in correctly positioning the dials withrespect to each other and with respect to the stock, removablefastenings passing through the openings in said dials and said rib, aspindle removably journaled in said dials having washers thereonabutting the inner surface of each dial, an arm extending from saidspindle intermediate the dials, a pendulum carried by said arm, pointersdetachably secured to said spindle at the ends thereof and movable oversaid dials.

In testimony whereof I afiix my signature.

HENRY J. BARNETT.
